ROTARY WATER-M ETER.

SPECIFICATION forming part of Letters Patent No. 34:3,804, dated June15. 1886.

Application filed Octobcrill, 1885. SerialNo.180,793. (No model.)

To all whom it may concern:

Be it known that I, GUSTAV FAJEN, of Milwaukee, in the county ofMilwaukee, and in the State of IVisconsin, have invented certain new anduseful Improvements in Fluid-Mecentral trunnions or shaft, 0 operativelyj ournaled in suitable bearings, a, centrally located at the point ofjuncture of the two sections D D, forming the outer casing of my meterQThese two casing-sections are provided with outwardly-extended flanges bb, which come in opposing contact and are perforated at suitableintervals to receive bolts 0, by which said sections are held in theirunited position, the joint thus formed being made tight by suit ablepacking interposed between the opposing flanges. One end of the lowercasing-section, D, at its highest point, is provided with an inlet, (1,adapted to receive a service-pipe, d, and the section D, on the endopposite the inlet d, is provided at its lowest point with an outlet, 0,designed to receive an exhaust-pipe, e. The section D is provided with achannel, E, the walls 9 of which form a seat for the drum A, and thischannel being of less width than the interior of the section the outersides of its walls and the inner sides of said section form gutters h,to receive sand or other deposits from the fluid.

The drum A is provided with a series of destructed to conform with thecontour of the channel E, thereby forming a flush and water tight jointbetween these parts when the drum is rotated. As the several gates areopened the shoulders on their ends t come against the periphery of thedrum, and thereby limit the movement of said gates-and retain them inoperative position with relation to the channel E. The shaft 0 isprovided with a gearwheel, 0, or its mechanical equivalent, designed toengage a corresponding gear-wheel, p, or equivalent, on the lower end ofa shaft, H, said shaft being adapted to communicate with any suitableregistering mechanism, in order that the amount of fluid passed throughthe meter may be automatically indicated. A bracket, 1", secured to theinterior'of the easing-section D, acts as the lower bearing for theshaft H, which latter also has a bearing in a suitable water-tightconnection, 8, at-the top of said section.

At the highest point of the casing-section D, where I locate the inletd, is a cut-off flange, I, having its inner end downwardly extended andpreferably terminated in an angular bend, 15, adapted to project intothe channel E, the downwardly-extended portion of the cutoff flangebeing immediately opposite to said inlet. The cutoff flange I isprovided with an upwardly-extended prong or web, it, which acts to closethe gates G at this point when-the drum A is rotated, and projectingfrom the inner side of the casing-section D is a lug, '0, designed tooperate the bell-cranks a, to open said gates after they have passed thepoint of inlet for the fluid.

In the operation of my invention, the several parts beingin the positionshown in Fig. l and fluid let on through the inlet d, said fluid willcome against the gate G, having its free end opened into the channel E,and by pressure will cause the drum A to rotate. As

this drum is rotated the gate held closed by the cut-off I passes theinlet and is opened into the channel E by its bell-crank a coming intocontact with the lug c on the casing-section D,

so that the pressure of the fluid is now eX- erted on this latter gateto continue the rotation of the drum. As the rotation continues fluid.The gates being equidistant apart, one of them will be brought andopened into the channel E before another has passed out of the latter,thereby forcing the drum to continue its rotation and prevent the fluidfrom rising above the inlet prior to exerting its pressure to operatesaid drum, and thus actuate the indicator mechanism to register thequantity of such fluid passed through said inlet. The drum will continueto rotate until a sufficient amount of fluid has entered to pass theoutlet 6 and fill the meter, the weight of this fluid operating to forcesaid drum tightly against its seat formed by the channel-walls 9, thuspreventing any escape into the meter until the outlet has been passed.As the fluid is drawn off from the outlet 6 the above-describedoperation is automatically continued, and the amount drawn indicated bythe registering mechanism designed to be connected -with the shaft 0 ofthe drum.

Having now fully described my invention,

/ what I claim as new, and desire to secure by Letters Patent, is-

1. A fluid-meter consisting of a suitable casing having inlet and outletopenings and its lower portion provided with a channel of less widththan the interior thereof, in combination with a rotary drum adapted tobe supported upon the channel-walls, and provided with hinged gatesdesigned to open into said channel, as set forth.

2. A fluid-meter consisting of a suitable casing having inlet and outletopenings and its lower portion provided with a channel of less widththan the interior thereof, and gutters formed by the channel-walls andcasing-sides,

by the channel-walls and the inner sides of angular bend, and anupwardly-projecting prong or web, a lug upon one of the inner sides ofthe meter-casing below the inlet,.and gutters formed by thechannel-walls and interior sides of the casing, an open-ended drumhaving a skeleton frame and trunnions or shaft journaled in suitablebearings, and a series of depressions, each provided at one end with asocket, a series of gates having perforated and shouldered ends designedto engage the socket ends of the depressions and their free portionshaped to conform with the interior of the channel, suitable rodsadapted to unite said gates to their respective depressions in the drumand provided with bell-cranks designed to come in operative contact withthe lug on one of the inner sides of the casing, and an indicatorshaftoperatively hung in suitable bearings, and provided with gearing adaptedto mesh with corresponding gearing on one of the journals of the drum,all constructed and arranged to operate substantially as and for thepurpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in

the county of Milwaukee and State of Wiscon- -85 sin, in the presence oftwo witnesses.

GUSTAV FAJEN. I
